The EMMAR 210 4B is a four-groove V-belt pulley for section B belts, with a 210 mm outside diameter. It is used to transmit power from a motor to a driven shaft, spreading the load across four belts. This pulley is manufactured in-house by MR Industrial Accessories and is intended for equipment that operates continuously and requires a balanced, machined pulley for proper belt seating.

The 210 4B pulley has a 210 mm outside diameter, four grooves and is designed for section B belts. The grooves are machined so that the belt seats evenly and stays in place. With four grooves, the load is distributed among four belts, which reduces wear on each belt and improves transmission when the equipment starts under load. The mass and diameter are set so that the pulley runs without troublesome vibrations within its operating range.

Typical applications include screw compressors, industrial fans, mills, mixers, conveyor belts and production machinery. It is also common in pumping equipment and in drives where speed needs to be reduced or increased between the motor and the driven shaft. Because it has four grooves, it is a frequent choice when more power must be transmitted without increasing the pulley diameter or changing the belt section.

For installation, check that the shaft and keyway are clean and free of burrs, and that the pulley slides on without force. Align the drive and driven pulleys with a straightedge or laser; misalignment of a few degrees will wear the grooves and belts. Tension the belts according to the equipment manual and recheck the tensioner after the first hours of operation. If the pulley uses a taper bushing, tighten the screws in a cross pattern with the correct wrench.

If you need a different number of grooves, another diameter or a different section, the pulley can be custom made. To request an equivalent, provide the original part number, the number of grooves, the belt section and the outside diameter. A photo of the mounted pulley and the shaft measurement also help. With that information, we can identify a similar pulley or manufacture it.

MR Industrial Accessories manufactures this pulley with dimensional control and balancing. To request a quote for the 210 4B pulley, send the part number via WhatsApp or email and we will reply with the technical information you need for your equipment.
